Question

Water is kept in a vessel at a temperature of 30°C .What would happen if a hot metal ball
having a temperature of 70°C is dropped in it .mention the heat flow.​

Answer 1

Answer:

The heat will transfer from hot metal ball to water containing vessel till they both termal equilibrium.

Explanation:

According to termal equilibrium heat will tranfer from hot body to cold body till they attain same degree of temperature

In this case the thermal equilibrium is =

30°+70°/2

100°/2

=50°

Answer 2

Answer:

Explanation:

Since there is a difference in temperature between the water and ball, and heat always flows from the body at high temperature to the body at low temperature therefore heat will flow from ball to water. The heat flow continues till both the bodies reach the equilibrium temperature. In this case it will be 50°C.
